Forza Motorsport 5 is "configurable" enough that the developer can add as many as ten new downloadable vehicles per month.
Game director Dan Greenawalt stated in an interview, “The game is very configurable. So we can add new tools and road locales and regions for like a van class,” then adding, “Being able to do monthly cars allows us to do wild cards like the transit van."
Having alternative vehicles is just a bonus of the software, Greenawalt stated. It will give Turn 10 the ability to release faster based on player feedback.
“And it’s not like it was a strategy like ‘let’s add wild things later’ – it just happens," he noted, "We get interest in it, we talk as a team. The nice thing is the game is so configurable that we can add things at will. We can add ten cars a month, just constantly releasing stuff, and the game will rearrange itself.”
Greenawalt described, “We have incredible depth across multiple axes. We have the depth of our garage diversity – we do traditionally have SUVs, cars, trucks, racecars, all sorts. We have the diversity in manufacturers – it’s not like we have 75 of some given manufacturer, we tend to really spread our bed across a lot of manufacturers. And we have a diversity of depth across time, because we do monthly updates of cars, because the car industry is always changing.”
Forza Motorsport 5 will be a launch title of the Xbox One, which has yet to be given a launch date.
